At the Closing, the Vendors agree that MoSys shall deposit 15% of the cash payable under Section 2.2 to the holders of Preference Shares other than the Virage Group and 15% of the cash payable under Sections 2.3 and 2.4 to the Continuing Shareholders listed on Appendix I of the Escrow Agreement (the “Major Continuing Shareholders”), with the Escrow Agent pursuant to and subject to the terms and conditions of the Escrow Agreement and Article 6 of this Agreement. Such Escrow shall remain in effect until the Last Escrow Claim Date.

2.7 Tax Election. At Closing, each Continuing Holder, at his or her sole option, may deliver duly completed and executed elections pursuant to Section 83(b) of the United States Internal Revenue Code (an “Election”), the form of which Election is attached as Exhibit C. MoSys covenants to file or cause to be filed such Elections with the Internal Revenue Service within 30 days after the Closing Date. Each Continuing Holder covenants to inform MoSys of any change in such Continuing Holder’s residency.

2.8 MoSys Stock and Cash Restriction Provisions. All cash payable and all shares of MoSys Stock issuable to a Continuing Shareholder pursuant to Section 2.3 or to a Continuing Optionholder pursuant to Section 2.4 is subject to the following restrictions:

(a) Each Continuing Shareholder and Continuing Optionholder (each a “Continuing Holder”) agrees to sign and deliver to MoSys at the Closing a Restricted Stock Purchase Agreement, the form of which is attached as Exhibit D, (the “RSPA”). Pursuant to the RSPA, all of the cash payable pursuant to Section 2.3(a) and 2.4(a) (“Restricted Cash”) and all shares of MoSys Stock issuable pursuant to Section 2.3(b) and 2.4(b) (“Restricted Shares”) shall be subject to forfeiture in the event that the Continuing Holder ceases to be employed by MoSys, Atmos or another Subsidiary of MoSys within three years after the Closing Date, as further described in this Section 2.8 and the RSPA. On the first anniversary of the Closing Date, the Restricted Cash shall cease to be Restricted Cash. On the last Business Day of every month after the first anniversary of the Closing Date until the third anniversary of the Closing Date, a portion of the Restricted Shares owned by a Continuing Holder pursuant to this Agreement, shall cease to be Restricted Shares in equal monthly instalments of 1/24 of each Continuing Holder’s Restricted Shares.

(b) Notwithstanding the schedule set forth in Section 2.8(a), if the employment of any Continuing Holder is terminated for cause, as defined in the RSPA, or is terminated voluntarily by such Continuing Holder prior to the first anniversary of the Closing Date, all of that holder’s remaining Restricted Cash and Restricted Shares shall be canceled and refunded to MoSys immediately upon such termination. If prior to such first anniversary, the employment of any Continuing Holder is terminated without cause, 50% of the Restricted Cash shall cease to be Restricted Cash and 50% of the Restricted Shares shall cease to be Restricted Shares, and the remaining Restricted Cash and Restricted Shares shall be canceled and refunded to MoSys immediately upon such termination. In the event that a Continuing Holder’s employment with MoSys, Atmos or another Subsidiary of MoSys ceases for any other reason while the Continuing Holder still holds any Restricted Cash or Restricted Shares, such cash shall be refunded to MoSys and such shares shall be forfeited to MoSys for cancellation by MoSys in accordance with the terms of the RSPA.

(c) The Continuing Holders acknowledge and agree that all shares of MoSys Stock will be held in escrow by MoSys, subject to the terms and conditions set forth in the RSPA.

(d) Notwithstanding the provisions of Section 2.3 and schedule set forth in Section 2.8(a), the cash paid and the shares of MoSys Stock issued to Paul Slaby and Wlodek Kurjanowicz shall be subject to restrictions in accordance with the terms of the Escrow Agreement, the RSPA and any employment agreement entered into by such individual and MoSys prior to the Closing.

2.9 Stock Option Issuance.

(a) MoSys will issue options to purchase a total of 300,000 shares of MoSys Stock immediately following the Closing to Continuing Shareholders (“MoSys Options”) who have signed this Agreement and become Vendors hereunder or have accepted the Share Purchase Offer and complied with all the provisions thereof. The exercise price of the MoSys Options will be equal to the closing price of a share of MoSys Stock on the Nasdaq National Market at the close of business on the Closing Date.

(b) The MoSys Options will be subject to the terms of the MoSys 2000 Employee Stock Option Plan (the “MoSys Option Plan”) and standard form of stock option agreement thereunder, which provide, among other things, for vesting of the options at the rate of 1/4 of the shares subject to the option on the first anniversary of the date of the option grant and 1/48 of the shares subject to the option at the end of each calendar month over the succeeding 36 months, subject to the optionee’s continuous employment by MoSys or a Subsidiary of MoSys. If a Continuing Shareholder ceases to be employed by MoSys, Atmos or another MoSys Subsidiary for any reason before all of his or her MoSys Options have vested, such options will not be exercisable as to the unvested portion of the shares at the date of termination, except as provided otherwise in the MoSys Option Plan.

2.10 Section 116 of the Income Tax Act (Canada).

(a) Each Vendor who is a non-resident of Canada shall, on or before Closing, deliver to MoSys a certificate (a “Section 116 Certificate”), satisfactory in form and substance to MoSys, issued by the Canada Customs and Revenue Agency pursuant to subsection 116(2) of the ITA in respect of the proposed disposition by the Vendor of his Common Shares, Preference Shares or Atmos Options, as the case may be. The Section 116 Certificate shall specify a “certificate limit” in an amount no less than the portion of the fair market value (expressed in Canadian dollars) as of the Closing of consideration payable to the Vendor (the “Vendor’s Consideration”).

(b) In the event that a Section 116 Certificate required under Section 2.10(a) has not been delivered by the Vendor to MoSys on or before Closing, or in the event that a Section 116 Certificate that is delivered by the Vendor to MoSys on or before Closing specifies a “certificate limit” that is less than the Vendor’s Consideration, MoSys shall be entitled to withhold on the Closing Date 25% of the Vendor’s Consideration owing to the Vendor under this Agreement, or such greater amount as will, in MoSys’s discretion, permit MoSys to satisfy its obligations under Section 116 of the ITA, which amount shall be converted into Canadian dollars on the Closing Date (the “Withheld Amount”). The Withheld Amount shall be deposited by MoSys in a trust account of their Canadian counsel Blake Cassels & Graydon LLP, which shall be invested in short-term interest bearing securities for and held for the benefit of the particular Vendor, and shall be remitted to the Receiver General of Canada on the day that the Withheld Amount is required to be so remitted pursuant to subsection 116(5) of the Income Tax Act (Canada) (the “Remittance Date”). The Remittance Date shall be extended if the Canada Customs and Revenue Agency issues a letter of extension for such remittance to MoSys. All interest received by Blake Cassels & Graydon LLP or MoSys on the Withheld Amount shall be for the account of the Vendor, and the full amount of such interest less any Taxes required to be deducted or withheld from such interest shall be paid to the Vendor on the Remittance Date. MoSys is hereby authorized to execute any documents and take any action as will enable it to satisfy its

liabilities and obligations under section 116 of the ITA, including the remittance of the Withheld Amount to the Receiver General of Canada under subsection 116(5) of the ITA. The balance, if any, of the Vendor’s Consideration will be released to the Vendor on the Closing Date.

(c) Notwithstanding the foregoing paragraphs (a) and (b), if the Vendor delivers a Section 116 Certificate or a replacement Section 116 Certificate to MoSys at any time after Closing and at least one Business Day prior to the Remittance Date and such certificate specifies a certificate limit in an amount no less than the Vendor’s Consideration, MoSys shall deliver the Withheld Amount together with all interest received by MoSys on the Withheld Amount less any Taxes required to be deducted or withheld from such interest, to the Vendor within three Business Days after the Section 116 Certificate is delivered to MoSys.

(d) In any case where MoSys and/or Blake Cassels & Graydon LLP withholds and remits to the Receiver General of Canada any amount pursuant to this Section 2.10, such withheld amount (prior to conversion into Canadian dollars) shall be treated for all purposes as having been paid to the Vendor on account of the Vendor’s Consideration, provided that the amounts so withheld have been remitted to the Vendor in question or to the Receiver General of Canada on its behalf and provided that the interest so required to be paid less any Taxes required to be deducted or withheld from such interest is paid to the Vendor in question.

2.11 Employee Amount. At Closing, MoSys will not withhold any portion of the consideration payable to a holder of Common Shares, subject to receipt of an appropriate tax opinion letter from KPMG; provided that if MoSys is assessed any payment, fine or penalty by Canadian taxation authorities for failing to withhold the amount (the “Employee Amount”) that is required to be withheld under the ITA on the amount of the aggregate amount of the employment benefit or benefits realized by such Employee under Section 7 of the ITA as a result of the transactions contemplated by this Agreement, such Employee agrees to pay MoSys the Employee Amount (including interest and penalties), and further agrees that MoSys may set off the Employee Amount against the Restricted Cash and Restricted Shares subject to the RSPA.

2.12 Employee Withheld Amount. On Closing, MoSys, or its designated Agent, will withhold from the portion of the consideration otherwise payable to a holder of Atmos Options the amount (the “Employee Withheld Amount”) that is required to be withheld under the ITA on the amount of the aggregate amount of the employment benefit or benefits realized by such Employee under Section 7 of the ITA (the “Employment Benefit”) as a result of the transactions contemplated by this Agreement. As soon as commercially reasonable following Closing, MoSys shall convert the Employee Withheld Amount into Canadian dollars at reasonable commercial exchange rates. MoSys will cause Atmos, and Atmos hereby agrees, to remit the Employee Withheld Amount to the appropriate taxation authorities on account of Canadian income tax payable by Employee in respect of the Employment Benefit. The Employee Withheld Amount shall be treated for all purposes as having been paid to the Employee on account of the portion of the consideration payable to such Employee.

All representations and warranties made under Sections 4.1, 4.2, and in the Vendors’ Releases, shall survive the Closing and any investigation with respect thereto by any party until the first anniversary of the Closing, or, if such anniversary falls on a day that is not a Business Day, the first Business Day following such anniversary (the “Last Escrow Claim Date”). Notwithstanding the foregoing, the survival period set forth in this Section 6.1 shall not prevent any Party from bringing a claim against any Party arising out of the knowing personal fraud or willful or reckless misconduct of such Party, which may be brought at any time permitted by the applicable statute of limitations.

6.2 Sole Recourse for Breach of Representations and Warranties. After the Closing Time, all rights, obligations and claims with respect to the representations and warranties made under Sections 4.1, 4.2 and in the Vendors’ Releases shall be determined exclusively in accordance with this Section 6.

6.3 Appointment of Holders’ Agent. The Vendors (other than the Virage Group, which shall act on its own behalf) hereby appoint Richard Boadway, or such other person as Mosaid may designate (the “Holders’ Agent”), to act as their agent for the purpose of representing and protecting their interests under this Agreement. Each Vendor (other than the Virage Group, which shall act on its own behalf) hereby appoints the Holders’ Agent as his attorney in fact, and agrees to be irrevocably bound by each election, decision and act of the Holders’ Agent. MoSys shall cooperate with the Holders’ Agent in connection with the reasonable performance of his responsibilities hereunder.

6.4 Indemnification by the Vendors and MoSys.

(a) Subject to Sections 6.1 and 6.5, each of the Vendors agrees, on a several basis (and not jointly or jointly and severally) and only in respect to the Personal Representations and Warranties given by such particular Vendor, to indemnify MoSys, and its respective shareholders, Affiliates, officers, directors, employees, agents, attorneys, contractors and their respective successors, assigns, heirs and personal representatives (collectively, the “MoSys Indemnitees”), severally, against and in respect of any and all Damages, either incurred directly by such Indemnitee or indirectly as a result of Damages incurred by any MoSys Indemnitee, which arise out of, result from or relate to any breach of or inaccuracy in any of the Personal Representations and Warranties made by such particular Vendor, or any representation or warranty in any certificate delivered by such particular Vendor to MoSys pursuant to this Agreement and from the breach by such particular Vendor of its Vendor Release. The parties acknowledge that, upon Closing, Atmos shall be deemed to be a MoSys Indemnitee.

(b) Subject to Section 6.5, MoSys shall indemnify each Vendor and their respective shareholders, Affiliates, officers, directors, employees, agents, attorneys, contractors and their respective successors, assigns, heirs and personal representatives (collectively, the “Vendor Indemnitees”) against and in respect of any and all Damages either incurred directly by such Indemnitee or indirectly as a result of Damages incurred by any Vendor Indemnitee, which arise

out of, result from or relate to any breach of or inaccuracy in any of the representations and warranties of MoSys contained in Section 4.2 or in any certificate delivered by MoSys pursuant to this Agreement.

6.5 Limitation on Claims.

(a) All Damages incurred by any MoSys Indemnitee shall be satisfied only from the Escrow Property (as defined in the Escrow Agreement), except as otherwise provided in this Section 6.5.

(b) No Vendor will be liable for Damages pursuant to Section 6.4(a) with respect to an amount in excess of the consideration paid to such Vendor.

(c) Notwithstanding Section 6.5(a), each Vendor shall be solely responsible for and shall indemnify the MoSys Indemnitees against and in respect of any and all Damages incurred by MoSys which arise out of, result from or relate to any breach of or inaccuracy in any of the Personal Representations and Warranties of such Vendor, or any breach of such Vendor’s Release, subject to the limitations on Damages set forth in this Section 6.5(b).

(d) Notwithstanding any provision of this Agreement to the contrary, the limitations set forth in this Section 6.5 shall not apply to a claim or Damages arising out of the knowing personal fraud or willful or reckless misconduct of a Party or its agents or any breach of such Vendor’s Release.

6.6 Notice of Claims. Any claim for indemnification pursuant to Section 6.4(a) shall be made by written notice from the MoSys Indemnitee to the Holders’ Agent in accordance with the terms of the Escrow Agreement or pursuant to Section 6.4(b) from the Holders’ Agent or the Virage Group to MoSys in accordance with Section 8.2; provided, however, that any claim in respect of the Personal Representations and Warranties, which are given on a several basis, shall be made by MoSys directly to the particular Vendor.

6.7 Disputed and Third-Party Claims.

(a) If any Party shall give notice of a claim in accordance with Section 6.6, and MoSys and the Holders’ Agent (or the particular Vendor acting on its own behalf, as the case may be) do not resolve such matter by written agreement within 45 days after such notice is given, the dispute will be settled exclusively by arbitration before a single arbitrator appointed by JAMS/Endispute. If the total amount (not including interest) of the dispute and any counterclaim exceeds $50,000, the arbitration will be conducted in accordance with the Comprehensive Arbitration Rules and Procedures of JAMS/Endispute; any other arbitration under this Section will be conducted in accordance with the Streamlined Arbitration Rules and Procedures of JAMS/Endispute. The arbitral award shall allocate the arbitrator’s fees and expenses according to the relative success of MoSys and the Holders’ Agent in the arbitration, as determined by the arbitrator.

(b) In the event of a claim by MoSys under Section 6.4(a) which, based on the relief sought by the claimant, can be fully satisfied by the available Escrow Amount (after deducting the full amount of all other pending claims for Damages) (a “Third-Party Claim”), Holders’ Agent (or the particular Vendor acting on its own behalf, as the case may be) will have the

option, exercisable by written notice to MoSys within 20 days after receipt of MoSys’s notice, to control the defense of such Third-Party Claim. All expenses (including, without limitation, attorneys’ fees) incurred by the Holders’ Agent (or the particular Vendor acting on its own behalf, as the case may be) in connection with his assumption of control of the defense of a Third-Party Claim shall be paid by the Holders’ Agent. If the Holders’ Agent (or the particular Vendor acting on its own behalf, as the case may be) has not so assumed the defense of a Third-Party Claim, then MoSys shall have the right to control the defense of the Third-Party Claim, and the expenses reasonably incurred by MoSys in connection with such defense shall be recoverable as part of the Damages which are the source of the underlying claim.

(c) In the event any claim alleging Damages in excess of the available Escrow Property (after deducting the full amount of all pending claims for Damages), MoSys shall have the sole right to control the defense of any such claim and the expenses reasonably incurred by MoSys in connection with such defense shall be recoverable as part of the Damages which are the source of the underlying claim.

(d) The party controlling the defense may use counsel selected by it to conduct such defense and shall notify the other party of such selection. If the other party reasonably objects within 20 days after designation of counsel initially selected that such counsel’s representation or potential representation of the designating party in matters in which MoSys’s and the Vendors’ or Atmos’s interests are adverse or potentially adverse, the designating party shall select other counsel free of any such adverse representation. The party controlling the defense shall have the right, in its discretion exercised in good faith and upon the advice of counsel, to settle such matter, either before or after the initiation of litigation, at such time and upon such terms as they deem fair and reasonable, provided that (i) at least 10 days’ prior notice shall be given to the other party of the intention to settle the Third-Party Claim, (ii) no settlement by the controlling party shall include any equitable relief binding on the noncontrolling party, and (iii) the controlling party shall not agree to any settlement of such Third-Party Claim without the prior written consent of the other party, which consent shall not be unreasonably withheld. The noncontrolling party will have the right to be represented by counsel, solely at its own expense. The controlling party shall keep the other party advised of the status of the Third-Party Claim and the defense thereof and shall consider in good faith recommendations made by the other party with respect thereto.

(e) Unless otherwise agreed by the Parties, arbitration of a claim by MoSys with respect to a Third-Party Claim shall be deferred until the resolution of the Third-Party Claim.

(f) Certain Specified Claims. The parties acknowledge and agree that Pixim and Atmos have asserted claims against one another with respect to the License and Services Agreement dated August 21, 2001 between Pixim and Atmos, which they have agreed to resolve by binding arbitration. All Damages to any MoSys Indemnitee from this dispute shall represent a claim against Escrow subject to the provisions of this Article 6. The net proceeds of any recovery by Atmos from Pixim in the arbitration proceeding shall be deposited into the Escrow and disbursed in the manner provided in the Escrow Agreement. MoSys agrees that counsel chosen by the Vendors will represent Atmos in the arbitration proceeding against Pixim, subject to the provisions of this Section 6.7. The parties further acknowledge and agree that all reasonable employee severance amounts that Atmos becomes obligated to pay after the Closing which arise from terminations which occur prior to the Closing in excess of the amounts set forth

in Schedule 6.7(f) attached, shall represent a claim against Escrow subject to the provisions of this Article 6.

ARTICLE 7 - ADDITIONAL COVENANTS OF THE VENDORS AND MOSYS

7.1 Non-Disclosure. Each Party agrees not to divulge or communicate, or use for any purpose other than evaluating this transaction or exercising rights as a Party hereto, any information or materials concerning this Agreement, the negotiation between the Parties hereto and the transactions contemplated hereby, except to the extent that such information (i) is or hereafter becomes lawfully obtainable from other sources, (ii) is required to be disclosed to a Governmental Agency having jurisdiction over the Party or its Affiliates, (iii) is otherwise required by law to be disclosed, (iv) is disclosed following a waiver in writing from the other Parties, (v) was known by the receiving Party prior to disclosure by the other party, or (vi) has been disclosed prior to the date of this Agreement.

7.2 Access. Between the date of this Agreement and the Closing or any earlier termination of this Agreement in accordance with its terms, each Vendor will (i) provide MoSys and its authorized representatives with such access to Atmos’s books, records, Properties, officers, attorneys and accountants as each such Vendor is authorized to obtain for himself and permit MoSys to make inspections and copies of such books and records, and (ii) furnish MoSys with such financial information and operating data and other information with respect to Atmos’s business and Properties as such Vendor possesses or is entitled to obtain, all as MoSys may from time to time reasonably request for the purposes of this Agreement, during normal office hours. MoSys shall give each Vendor reasonable advance notice of any on-site visit, and such Vendor shall have the right to cause the agents of MoSys to be accompanied by an officer or designated employee of such Vendor.

7.3 Reasonable Business Efforts, No Inconsistent Action. Each Party will use its reasonable business efforts to cause the conditions over which it has control to be satisfied on or before the Closing; provided that MoSys shall not be obligated to consent to or waive compliance with any matter specified as requiring its consent in Section 3.2. No Party will take any action which will foreseeably result in the failure to satisfy any condition stated in Section 3.2 or 3.3 on or before the Closing.

7.4 Indemnification of Atmos Indemnitees. The Vendors agree that all rights to indemnification for acts or omissions occurring prior to the Closing Time in favor of the directors or executive officers of Atmos (the “Atmos Indemnitees”) as provided in Atmos’s certificate of incorporation or bylaws, in effect immediately prior to the Closing Time or granted by contract shall terminate at the Closing Time, except as to claims brought against the Atmos Indemnitee as an agent of Atmos (i) if such Atmos Indemnitee had knowledge of such claim or the basis of such claim as of the date of the Closing, (ii) such claim has been disclosed on the appropriate schedule to this Agreement, and (iii) such claim would not constitute a breach of any representation or warranty under Section 4.1 or in the Vendors’ Releases.

7.5 Termination of this Agreement.

(a) MoSys may terminate this Agreement prior to Closing and the transactions contemplated hereunder in the event (i) of any breach of any covenant of a Vendor under this Agreement, (ii) any closing condition under Section 3.2 is not satisfied prior to August 31, 2002,

(iii) of material default hereunder by any Vendor, or (iv) of mutual agreement by MoSys and the Principal Vendors to terminate this Agreement and the transactions contemplated hereunder. Termination of this Agreement and the transactions contemplated hereunder by MoSys for any other reason will constitute an abandonment of such transactions by MoSys.

(b) If any condition stated in Section 3.3 is not satisfied prior to August 31, 2002, then, provided the Vendors are not in material default hereunder, the Vendors and the Holders’ Agent may at any time thereafter terminate their respective obligations under this Agreement including, as applicable, under or arising from any exhibits, certificates and schedules thereto by giving written notice thereof to MoSys. No Vendor may terminate this Agreement or abandon the transactions contemplated hereunder for any other reason.

7.6 Termination of Other Agreements. The parties hereto acknowledge and agree that, in conjunction with the payments to be made to the Virage Group hereunder and the sale of all of its interest in Atmos, the various agreements and arrangements between the Virage Group and Atmos (the “Virage Agreements”) shall be terminated, and, as contemplated by the Mutual Release to be delivered on Closing as provided for in Sections 3.2(i) and 3.3(d)(vi) hereof by some of the parties hereto and certain others, including Atmos, each of the parties hereto hereby covenants and agrees to release each other from any claims or accrued entitlements under the Virage Agreements (known or unknown) subject to the terms of this Section 7.6.

(a) The Vendors agree that all of their respective rights and obligations under that certain Share Purchase Agreement dated as of June 29, 2001 among Atmos, Virage and certain other purchasers, the Atmos Shareholders’ Agreement and the Share Purchase Option Agreement will be terminated, canceled and without force or effect immediately after the Closing Time and no party thereto shall have any ongoing rights, obligations, claims or entitlements thereunder.

(b) With respect to that certain Technology License Agreement made as of June 29, 2001 among Atmos, Virage and Mosaid, the parties hereto acknowledge and agree that the License contemplated therein never became effective (as provided in Section 2.5 of such agreement), that Virage was never given access to the technology and “Atmos Intellectual Property” contemplated thereunder and, accordingly, such agreement will be terminated effective as of the Closing of the transactions herein contemplated and no party thereto shall have any ongoing rights, obligations, claims or entitlements thereunder.

7.7 Exclusivity. Between the date of this Agreement and the earlier of the Closing Date and the permissible termination of this Agreement and abandonment of the transactions contemplated hereby pursuant to Section 7.5 (a) or (b), the Vendors, and each of them, agree not to enter into any agreement with respect to an Acquisition Transaction or commence, continue or conduct any discussions, directly or indirectly, with any other party concerning any Acquisition Proposal.

7.8 MoSys Contribution. At the Closing, MoSys agrees to contribute $200,000 to Atmos which MoSys shall cause to be paid at the Closing to Virage by Atmos for license fees owed by Atmos to Virage.
